The service lateral is a system of wires which form a path over which electricity is carried from the main line to the house. This is generally built by the utility company and its cost will depend upon the distance of the residence from the main line and whether the owner furnishes poles, labor, etc.
Wires should be of such size as to give sufficient mechanical strength to stand up under sleet conditions. Usually three entrance wires are used to carry the electric energy from the utility connection to the house. The lateral is the electrical doorway to the farm and is the most essential part of the wiring system. The wires should be of adequate size so as to provide proper voltage and give complete electrical service for all ordinary requirements of current.
It is important to see that the electrical equipment is properly “grounded,” that is, the connecting to earth of certain metallic objects which are near power conductors. The purpose is to carry to the earth any heavy electrical charge which might exist on such objects and cause electrical shocks when they are touched. Grounding may be secured by connecting with water pipes that reach some depth under ground, or driven pipe may be used as a means of securing intimate contact with moist earth.
Recommendations for outlets from the electrical wires in the house call for centering ceiling lighting outlets, and placing wall brackets about 5½ feet above the floor. Convenient outlets in the kitchen and bathroom should be about 33 inches above the floor. In other locations they are usually best placed in the baseboard. Wall switches are usually located 4 feet above the floor. A switch should be located at each door to a room or entrance to a hall and in many cases three-way switches can be used to advantage, since these afford control over the same lighting from two separate locations.
With these general observations on a rather complicated subject, most of which are based on the excellent recommendations of the National Committee on the Relation of Electricity to Agriculture, the home owner should be in a position to take care of his needs properly, bearing in mind that the system of wiring should be adequate in every respect and the number of outlets sufficiently numerous to provide easy and convenient service throughout the house. An official check-up should be made of all installations after completion. The method of securing such inspection can be obtained through a local electrical contractor.

Tank Gas Supply.—A service of supplying compressed gas in portable tanks has recently been developed for country homes located away from public gas lines. This gas can be used either with a specially adapted range which is supplied as part of the service or in some cases with an ordinary gas range. Companies offering this service are located in most cities and are understood to be willing to supply residences anywhere with gas. The cost of first installation of the system is about $40. Renewals cost approximately $12 per cylinder of gas. Each cylinder will supply a family of four with gas for three to four months, making a monthly bill of from $3 to $4, which compares favorably with artificial gas supply through a meter from pipe lines. This gas may be used for any purpose for which any other gas is adapted. The gas and the servicing of it constitute a boon to country residents from the standpoint of utility and economy. It is especially desirable for those previously accustomed to city gas supplies and to whom the use of any other type of fuel is strange and somewhat of a problem.
